MUSlCAL BOX.

SPECIFICATION forming part of Letters Patent No. 268,2

K2, dated November 28, 1882,

Application filed August Q4, i882. (No model.) Patented in Germany July 1l, 1381, NoA 27,520.

To all whom it may concern Beit known that I, ERNEST PAILLARD, ot'

Sainte-Croix, Canton de Vaud, Switzerland, have invented certain new and useful Improvements in Musical Boxes, (for which I obtained Letters Patent in Germany, No. 27,520, and bearing date the 11th day of July, 1881,) of which the following is a specitication.

This invention relates to musical boxes, and has for its object to improve and simplify the device for causing the pin studded barrel to assume different longitudinal positions, and known as the air or tune changer.77

The invention consists of a cog-plate pivoted at right angles to the axis ot' the pin-barrel, on the side ofthe bearing which supports the outer end of it, said cog-plate being so arranged that the end ot' the pin barrel is caused to bear against the edge ot' one ot' the cogs by means ot' a spring or other yielding device. A pin secured in the outer end ot' the barrel comes in contact with the tooth or cog ofthe cog-plate against which the end ofthe barrel presses, and so causes the cog-plate to turn one tooth each time the barrel makes a revolution, and during the interval when the blank space between the actuating-pins -on the barrel is opposite the comb of keys. The teeth of the cog-plate vary in length, sothat the barrel is held in different longitudinal positions when retained in position by the different teeth or cogs,thereby bringing the va-rious sets of pins on the barrel adapted to play different times consecutively opposite the ends vof the keys.

But to describe my invention more particularly, I will now refer to the accompanying drawings, formingpart of this specification, in which- Figure l is a plan view of a musical instrument embodying my improvements. Fig. 2 is a side elevation ot thesame, showingafront View ot'thecog-plate. Fig.3isanendelevation. Fig. 4 is a part side elevation, showing the tunechanger in operation; and Fig. 5 shows a modification in the form of the cog-plate. l

The main trame a, comb ot' keys b, and springmotor c, as well as the general construction ot' the pin barrel d, are as ordinarily madethat is to say, the gear-wheel e on the springdrum meshes into tho pinion j', secured to the pin-barrel shalt or spindle g, the piu-barrel d being iitted loosely on the said shaft,but caused to rotate therewith by means ofthe stud or pin lz, secured to the iiange 1'., and entering a hole in the end ot' the barrel d. Between the end of the barrel d and flange fi, on the shaft g, is placed a spring, j, which keeps the other end ofthebarrel against my improved tune-changer, which consists simply ot' the cog-plate 7.', fitted to rotate on a screw or stud on the side ot' the bearing-block l for the outer end ofthe barrelshaft g. This cog-plate k is at right angles to the axis ot' the barrel, so that the end of the barrel is caused by the springj to press against one ot' its teeth or cogs, said teeth oreogs having flat edges ot' sntticient width to cause the cog-plate to retain its position by the pressure ot' the end of the barrel on the cog adjacent thereto, thereby retaining the barrel in a fixed longitudinal position until the cog -plate is partly rotated to present another cog to the end ol' the barrel. This rotation ot' the cog-plate k is accomplished by means of the piu or stud m, secured in the end of the barrel d, coming in contact with the cog, as shown in Fig. 4, and so turning the cog-plate k to bring the succeeding oog against the end ot' the barrel d.

The cog-plate 7; is rotated by the pin m when the blank space on the pin-barrel dis opposite the end ol" the keys b. To insure the proper action oi' the cog-plate whenbeing partly rotated by the pin fm, a slight depression, n, (shown in Fig. 3, and in dotted lines in Fig. 4,) is made in the end ot' the barrel, just behind the pin m, and into which depression the front corner o1 the cog being brought into action enters as the cog-plate is rotating.

The longitudinal position ot' the barrel d in relation to the keys I) is determined and governed by thc height of the teeth or cogs ofthe cogplate 7.?, which is pxovided with as many teeth or cogs as there are sets ot' pins on the barrel (l, or equal to the number of tunes the instrument is designed to render, or a multiple ot' the same. In the figures ofthe drawings 1 95 to et the cogplate It' is shown as designed to move and hold the barrel din two longitudinal positions only, the diametrically-opposite teeth or cogs being ot' the same length.

In Fig. 5 a tour-toothed cog-plate 7c is shown, roo

cach varying in length, the saine being' adapted for afour-tuneinstrument. rlhese teeth gradually increase in height in consecutive order. They may be arranged in any order desired, and it is obvious that a tune-changer may be constructed on this principle with any number of teeth, according,` to the requirements of the instrument to which it is applied, and said innprovements may be applied to both large and small musical boxes.

Having now described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In an air-changer for musical boxes, the combination of a Variable-toothed cog plate, fitted on a. fixed block, to rotate at right angles to the axis ofthe pin-barrel, with the pin-barrel, and a stud or pin on its end adapted to turn the cog,` -plate one tooth at each revolution of the barrel, substantially as and for the purpose set forth.

2. rEhe sprin ,fg-actuated pin-barrel d, provided with the stud or pin mi, and a depression, n, in combination With the cog-plate 7s, pivoted on the bearing-block l, at right angles to the axis of the pin-barrel, substantially as and for the purpose set forth.

ln testimony whereof' I have hereunto set my hand, at Sainte-Croix, Carlton de Vaud, Switzerland, lthis 21st day of July, A. D. 1882.
